Kling 3.0 - AI Model API and Pricing

Shots where physics has to convince

Its listed strengths are physical motion at 1080p and reliable object interaction. Use it for a hand turning a bottle to show its label, or a sneaker landing in a puddle. Other good fits are a chef flipping a pancake and a character dancing without limbs sliding through each other. These are the shots where cheaper models give away that the video is generated.

Which of the six tools to open

AI Video Generator and Text to Video start from words. Product turn and Coffee pour are presets that suit its handling strengths. AI Camera Motion takes an image and moves the camera. Choose Drone orbit, Slow dolly in, Whip pan or Bullet time. AI Video Effects turns a still into Explosion, Shatter or Melt. Animate Character takes an image or a video and applies Wave hello, Walk cycle or Dance. AI Dance Generator animates a photo with routines from Hip-hop groove and Salsa to Pet groove.

This text prompt leans on physics: "Close-up of a hand pouring cold brew over ice in a clear glass. Ice cubes shifting as the liquid rises, condensation on the outside, slow push in."

Settings that save credits

Choose 16:9 for web and YouTube, 9:16 for Reels and Shorts, 1:1 for feed posts. Draft at 720p and 5 seconds; move to 1080p and longer clips only once the motion reads correctly. Clips come back silent here, so plan the soundtrack separately, for example with Sound Effects.

Clip costs at each length

A 5-second clip costs 135 credits, about $1.44 at the best pack. 10 seconds costs 270 credits, about $2.87. The full 15 seconds costs 405 credits, about $4.31. It is 22nd from the cheapest of 31 per-second video models.

When another model fits better

Seedance 2.5 costs the same 27 credits per second and suits long single takes with spoken dialogue. It also suits work with many reference files, but tops out at 720p on Ugesi. Veo 3.1 Fast, at 36 credits, is the pick for Veo behavior at a mid budget. Sora 2 is listed at 24 credits, but its API shut down on September 24, 2026. Do not plan around it.
